目的　本文报告 32例乳头旁憩室 ,旨在强化临床的诊断意识 ,从而提高术前诊断水平。方法　收集了胆胰管疾病行手术和T型管引流术后造影 990例和钡检 1例 ,总计 991例。结果　检出乳头旁憩室 32例 ,其中发现Ⅰ、Ⅲ型中有两个亚型 ,分别为Ⅰa型 ( 3例 ,9.37% )、Ⅰb型 ( 2例 ,6.2 5 % ) ;Ⅲa型 ( 9例 ,2 8.12 % )、Ⅲb型 ( 6例 ,18.75 % )。结论　凡有胆胰管疾病的患者 ,术前应常规作上消化道钡餐检查和T型管引流术后造影 ;在检查中应用动态观察是减少术前、术后漏查、漏诊的关键技术。 Objective This article reports 32 cases of papillary diverticulum, aimed at strengthening the clinical diagnostic awareness, thereby enhancing the level of preoperative diagnosis. Methods Collected 990 cases of biliary and pancreatic duct diseases and T-tube drainage after surgery and barium examination in 1 case, a total of 991 cases. Results There were 32 cases of papillary diverticulum. There were two subtypes of type Ⅰ and Ⅲ, which were Ⅰa (3 cases, 9.37%), Ⅰb (2 cases, 6.25% , 2 8.12%), type Ⅲ b (6 cases, 18.75%). Conclusions All patients with biliary and pancreatic duct diseases should be routinely performed upper gastrointestinal barium meal examination and T-tube drainage postoperatively before operation. Dynamic observation is the key technique to reduce preoperative and postoperative missed inspection and missed diagnosis.
